WASHBOILER.

SPECIFICATION forming part of Letters Patent No. 758,867, ed May 3, 1904.

Application filed November 5, 1903. Serial No. 179,883. (No model.)

To (all whom it may concern:

Be it known that we, AXDREWW'. SNYDER,

residing in the city of Richmond, and l/VAL'IER Q MCCONAHA, residing near Centerville, in the county of \Yayne and State of Indiana, citi- Zens of the United States, have invented new and useful Improvements in \Vashboilers, of which the followingis a specification; and we do hereby declare the following to be a full, clear, and complete description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention has particular reference to washboilers for cleaning fabrics by the action of steam and hot water, whereby the action of heat will cause the water and steam to circulate through the fabrics, involving in its principle the expansive force of steam and siphoning to move the water upward and the movement by gravity of the water in its downward or return course to complete the circuit.

The object of our invention, broadly speaking, is the provision of an improved device of the class described which will thoroughly cleanse an amount of textiles placed therein by the action of water supplied thereto and maintained at a high degree of temperature by the action of heat.

The primal object of this our present invention is to provide a washboiler in which a constant circulation of hot water may be established and maintained from the lower or steam-generating space upward through columns at either end of the boiler and discharged in a cascade on top of the articles to be cleaned to percolate therethrough and return by gravity to the steam-space through conduits on the under side of the false bottom.

Another object is to provide a vashboiler which will effectually remove all dirt and stains from fabrics by the circulation of hot water therethrough and that without a particle of labor on the part of the attendant other than that required to place the articles in the boiler and to remove them therefrom after the work is accomplished and to maintain the l heat necessary to retain the water at the de- 1 sired temperature for the work to be accomplished. 5

Another object is to provide a washboiler of the class indicated above. in which there are no points or edges by which fabrics might be damaged and in which means are provided for readily removing the accumulation of sediment, lint, or the like from the columns and conduits and from beneath the false bottom.

Another object is to provide a simple, durable, and positive means for cleaning textile fabrics which will be compact in form and construction, easily operated and controlled in order that its work will be performed with certainty and precision and with a minimum of time and labor devoted thereto.

Another object is the provision of an arti- 5 cle of manufacture in a washboiler of new and improved construction which can be manufactured and sold at a comparatively low price and with the assurance that its work will be performed with accuracy and satisfaction.

Other specilic objects and advantages of our invention will he made manifest from the following specification, and the operation and construction shown in the drawings will visualize for any one inspecting them.

Our invention consists, primarily, in a washboiler embodying certain new and useful features and details of construction and disposition of the several interdependent and cooperating parts, substantially as hereinafter par- 80 tic ularl y set forth, illustrated in the drawings, and incorporated in the claim hereunto appended.

The invention relates to washboilers, substantiall y as shown in the accompanying draw- 5 ings, in which w Figure l is a vertical longitudinal section of the entire apparatus as taken on the line X X of Fig. Fig. 2 is a vertical cross-section of the entire apparatus as taken on the 9 line Y Y of Fig. l). Fig. 3 is a plan view of the invention taken on line Z Z of Fig. 1. Fig. 4. is a detail perspective somewhat enlarged and showing a portion of same parts as Figs. 1 and 2. Fig. 5 is a detail isometrical View of one of the guards or covers for the columns located at the ends of the boiler.

Similar indices refer to and denote like parts throughout the several views of the drawings.

In the drawings the letter A denotes the two sides, B the two ends, C the bottom, and D the cover, of a washboiler, which parts are of the usual form and construction and together form the basic parts for our improvements.

The numeral 1 denotes the perforated false bottom, permanently secured to the sides of the body of the boiler at a point some distance above the bottom C. The perforations 2 are interspersed at frequent distances apart in rows through the false bottom, as shown in Fig. 3.

Y On the under side of the false bottom 1 are secured and suspended therefrom two aggroupments of conduits 3, each of which commence at a point near the end of the false bottom and enlarge uniformly to their inner ends, forming mouths near the center of the boiler. Each of the two aggroupments of conduits consists of aplural equal number thereof, and the conduits of one aggroupment are arranged alternately and extend slightly beyond or overlapping the conduits of the oppositelydisposed aggroupment, substantially as indicated in Fig. 3. It will be obvious that by the said arrangement of the conduits the discharges of one series will be in a direction opposite to that of the other series and also that the discharges of each series will be beyond the discharges of the other series, thus allowing the water passing through one series to be discharged under and beyond the other series, thus resulting in a thorough mixing of the water and also in the discharge of the cooler water from above being discharged near the heated parts of the boiler. The perforations 2 are so disposed that they all open into said conduits an equal number in each and disposed with reference to each other, substantially as illustrated in the drawings.

It will be observed that the false bottom 1 does not cover the extent of surface, as does thebottom C, but that at each end the false bottom extends only to or slightly beyond the beginning of the condure of the ends B, thus leaving an interstice between the ends of the false bottom and the walls of the ends B.

Extending upward at right angles from the ends of the false bottom 1 are the diaphragms 4, whose upward extension is to a distance somewhat below the upper edge of the boiler proper, and whose sides are secured to the body of the boiler, forming a column or viaduct'from the space below the false bottom leading to near the top of the boiler, as shown. The upper horizontal free edges of the diaphragms 4 are doubled over upon themselves in order (a) to stiffen and. support their edges and (b) in order that they may present smooth rounded edges.

The numeral 5 represents channel-cleats secured to the inside walls of the ends B and disposed at an angle, their ends being secured slightly above the upper ends of the diaphragms 4, and the centers being secured somewhat higher and at all points contacting with and secured to the body of the boiler, as shown.

The numeral 6 denotes a gate or cap having a straight inner edgeturned upward and back upon itself in order (a) to stiffen and support their edges and (Z2) in order that they may present smooth rounded edges. From the ends of said edges the gates are formed in the segment of a circle corresponding with the contour of the ends of the boiler to which they are secured and are adapted to fit in thegroove of said channel-cleats, and when the gates are positioned in their channels, as shown in the drawings, interstices 7 are formed which provide the only means of egress from the viaducts 8 upward to the interior of the boiler.

In-practice the fabrics to be cleansed are deposited in the boiler, covering the bottom, and should fill the space thereof to near the interstices 7. Water is then placed in the boiler to a determined sufficiency, for instance, rising to a point somewhat below the tops of the diaphragms 4. The boiler is then placed on a stove or range,whereby heat may be applied to the bottom C. As the water below the false bottom becomes heated and expands it will be forced up the'viaducts 8, these being the points of least resistance, and will be discharged through the interstices 7 in a fountain-like cascade over and on the fabrics contained by the boiler, and through said fabrics the water will percolate by gravity to the false bottom, passing through the perforations 2 into the conduits 3, and from the mouths of the latter it is deposited in the space below the false bottom in alternately oppositely directed streams to be again heated and returned in its circuit as before. The action of the heat and the hot water percolating through the fabrics will remove every particle of dirt therefrom without any strain or wear whatever on the fabrics.

It will be apparent that after the fabrics and water have been removed from the boiler the gates or caps 6 may be removed, whereby access may be obtained to the viaducts for the removal of accumulations of dirt, sediment, and lint from below the false bottom. It will be observed that the diaphragms and interstitial mouths 7 are oppositely disposed and that the discharges will be toward the center of the boiler, whereby the water will be evenly dispersed over the fabrics contained in the boiler.

By means of our invention the cleansing of IIO the fabrics is effectively accomplished with a minimum of time and labor and with a maximum of efliciency.

\Vhile we have shown and described the best means to us known at this time for carrying out our invention in a practical manner, we desire it to be understood that we do not restrict ourselves to the exact details of construction shown and described, but hold that any changes or variations therein as would suggest themselves to the ordinary mechanic would clearly fall within the limits and scope of our invention.

Having now fully shown and described our invention, what we claim, and desire to secure by Letters Patent of the United States, is

In a \vashboiler, the combination with a receptacle having a perforated false bottom of less length than the boiler permanently secured above the main bottom, a pair of diaphragms secured to the respective ends of the false bottom and extending up to near the top of the boiler and permanently secured to the walls of the boiler, a gate slidably and removably mounted at an angle over the upper end of each of the spaces formed between said diaphragms and the ends of the receptacle, a double series of oppositely-disposed acuminate conduits secured to the under side of the false bottom and having communications with the interior of the receptacle through all of said perforations and having their dischargemouths alternately arranged near the center of the space below the false bottom and overlapping each other, all substantially as shown and described and for the purposes set forth. In testimony whereof we have hereunto signed our names to this specification in the presence of two subscribing witnesses.
